ALURE is a utility library to help manage common tasks with OpenAL applications. This includes device enumeration and initialization, file loading, and streaming.

Gnaural is a programmable auditory binaural beat synthesizer intended to be used for brainwave entrainment. Gnaural supports creation of binaural beat tracks of different frequencies and exporting of tracks into different audio formats. Gnaural can also be linked over the internet with other Gnaural instances, allowing synchronous sessions between many users.

RtOSC is a realtime safe library for handling OSC messages.

Sratom is a library for serialising LV2 atoms to/from RDF, particularly the Turtle syntax.

Tao is a software package for sound synthesis using physical models. It provides a virtual acoustic material constructed from masses and springs which can be used as the basis for building quite complex virtual musical instruments. Tao comes with a synthesis language for creating and playing instruments and a C++ API for those who would like to use it as an object library.

OpenCore-AMR is a library of OpenCORE Framework implementation of Adaptive Multi Rate Narrowband and Wideband (AMR-NB and AMR-WB) speech codec.

clalsadrv is a C++ wrapper around the ALSA API simplifying access to ALSA PCM devices.

This package provides python bindings for libsndfile based on CFFI and NumPy.

cyanrip is a command line tool for ripping CDs. It uses MusicBrainz to name and tag each track, and to download and embed cover art. cyanrip supports encoding tracks to multiple formats in parallel and automatically verifies checksums.

midicomp can manipulate SMF (Standard MIDI File) files. It can both read and write SMF files in 0 or format 1 and also read and write its own plain text format. This means a SMF file can be turned into easily parseable text, edited with any text editor or filtered through any script language, and recompiled back into a binary SMF file.

lv2lint is an LV2 lint-like tool that checks whether a given plugin and its UI(s) match up with the provided metadata and adhere to well-known best practices.

This package contains the resample and windowfilter command line utilities. The resample command allows changing the sampling rate of a sound file, while the windowfilter command allows designing Finite Impulse Response (FIR) filters using the so-called window method.

Jalv is a simple but fully featured LV2 host for JACK. It runs LV2 plugins and exposes their ports as JACK ports, essentially making any LV2 plugin function as a JACK application.

Csound is a user-programmable and user-extensible sound processing language and software synthesizer.

Carla is a modular audio plugin host, with features like transport control, automation of parameters via MIDI CC and remote control over OSC. Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2, and VST3 plugin formats, plus SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA.

The mbelib library provides support for the 7200x4400 bit/s codec used in P25 Phase 1, the 7100x4400 bit/s codec used in ProVoice and the Half Rate 3600x2250 bit/s vocoder used in various radio systems.

Libzita-resampler is a C++ library for resampling audio signals. It is designed to be used within a real-time processing context, to be fast, and to provide high-quality sample rate conversion.

Pure Python bindings for Augeas.

Augeas is a library and command line tool for programmatically editing configuration files in a controlled manner. Augeas exposes a tree of all configuration settings and a simple local API for manipulating the tree. Augeas then modifies underlying configuration files according to the changes that have been made to the tree; it does as little modeling of configurations as possible, and focuses exclusivley on transforming the tree-oriented syntax of its public API to the myriad syntaxes of individual configuration files.

The OATH Toolkit provides various components for building OTP authentication systems:

• oathtool, a command-line tool for generating & validating OTPs.

• liboath, a C library for OATH handling.

• pskctool, a command-line tool for manipulating secret key files in the PSKC format described in RFC6030.

• libpskc, a shared and static C library for PSKC handling.

• pam_oath, a PAM module for pluggable login authentication.

Supported technologies include the event-based HOTP algorithm (RFC4226), the time-based TOTP algorithm (RFC6238), and PSKC (RFC6030) to manage secret key data.

The Yubico PAM module provides an easy way to integrate the YubiKey into your existing user authentication infrastructure.

Pamtester is a tiny utility program to test the pluggable authentication modules (PAM) facility, specifically designed to help PAM module authors to intensively test their own modules.

This package provides a library to generate HOTPs as specified in RFC 4226 and TOTPs as specified in RFC 6238.

oauth2l (pronounced ``oauth tool'') is a simple command-line tool for working with Google OAuth 2.0 written in Go. Its primary use is to fetch and print OAuth 2.0 access tokens, which can be used with other command-line tools and scripts.
